hey is there a way to munge the extracted version of the unmunge back together after it was extracted?

for example if you have ingame.lvl and extract it with unmunge, you get 6 folders
config
effects
msh
munged
odf
texture

if i wanted to change a value in a hud-file which is in config and want to put it back together into a ingame.lvl file, how would i do that?
